Tendera

AI girlfriend chat with four written, real characters

Visit

Tendera is a small AI girlfriend and AI companion app built around a single idea: characters who feel like specific written people are more interesting than characters you configure.

Instead of offering a hundred shallow personas or a trait-slider to build your own, Tendera gives you four hand-written characters — Sophia, Mia, Elena, and Jade — each with her own voice, backstory, Tuesdays, and way of listening. They remember your conversations, stay in character across sessions, and respond in their own voice rather than the generic tone most chatbots default to.

If none of the four move you, a custom character creator lets you write someone you'd rather meet — as a writing exercise, not a shopping cart.

The product is built for people who want a conversation that feels like meeting someone, not operating a bot. Free to try with five messages, no signup required. After signing up, you get 25 free messages per day with all four characters.

Built by a solo founder who cares more about character depth than feature breadth.

ey — I'm Bill, solo founder of Tendera. I came from the gaming industry. That's where I learned the thing people come back for isn't features or graphics — it's characters they can't stop thinking about. Most AI companion apps go the opposite direction: 100+ characters, voice calls, image generation, surface that demos well. I think they're solving the wrong problem. What users actually want is someone who feels specific, remembers what they said last week, and doesn't dissolve into a generic tone after the third message. Tendera is 4 hand-written characters — Sophia, Mia, Elena, Jade — each with a system prompt I've rewritten maybe 20 times. No voice. No image. Text only, by design. Closer to meeting someone from a novel than operating an AI girlfriend generator. Would love to hear what you think, good or bad. — Bill
